Abstract

A sliding bearing forced air cooling structure of a high-speed self-lubricating motor comprises a machine base. A front sliding bearing pedestal and a rear sliding bearing pedestal are arranged at the two ends of the machine base respectively. A rotary shaft is rotationally connected between the front sliding bearing pedestal and the rear sliding bearing pedestal. A cooler is arranged at the top of the machine base. A fan hood is arranged at the rear end of the machine base. An outer fan connected with the rotary shaft is arranged in the fan hood. An air cooling channel is arranged in the machine base in the axial direction. A vent hole is formed in the lower portion of the front side of the fan hood. The rear end of the air cooling channel is connected with the vent hole through a rear connecting pipe. The rear connecting pipe is provided with a rear air cooling pipe blowing air to the rear sliding bearing pedestal. A front connecting pipe is arranged at the front end of the air cooling channel. The front connecting pipe is provided with a front air cooling pipe blowing air to the front sliding bearing pedestal. The heat dissipation capacity of the bearing pedestals at the two ends is improved, the work temperature of sliding bearings is reduced, and the operation reliability of the bearings is improved.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a forced air cooling structure of a sliding bearing of a high-speed self-lubricating motor. Background technique [0002] Because high-speed self-lubricating motors do not require an external circulating oil system, they have the advantages of low initial investment in equipment, convenient installation and maintenance, and easy operation and monitoring of operating status, so they have been widely used in modern industries. In the known technology, the heat generated by the friction between the bearing bush and the shaft of the self-lubricating motor is mainly dissipated by the natural convection heat exchange between the bearing seat and the air in the environment. Due to the low natural convection heat dissipation efficiency of the bearing seat, the heat generated by the bearing cannot be dissipated in time, resulting in high-temperature deterioration of the lub...
